 * Developers wanting to explicitly tag a class as a JUnit 4 class should use
 * {@code @RunWith(JUnit4.class)}, not, for example in JUnit 4.5,
 * {@code @RunWith(BlockJUnit4ClassRunner.class)}. This is the only way this class should be
 * used--any extension that depends on the implementation details of this class is likely to break
 * in future versions.
